Editing LINC (section)

== Control panel ==
The LINC control panel is used for single-stepping through programs and for program [[debugging]]. Execution can be stopped when the [[program counter]] matched a set of switches. Another function allows execution to be stopped when a particular address was accessed. The single-step and the resume functions can be automatically repeated. The repetition rate can be varied over four orders of magnitude by means of an analog knob and a four-position decade switch, from about one step per second to about half of the full speed. Running a program at one step per second and gradually accelerating it to full speed provided an extremely dramatic way to experience and appreciate the speed of the computer.
